Political risk in France has shifted from a largely ignored tail risk into a tangible risk premium for European assets, and the renewed turmoil is hitting the country’s banking sector hard. Following President Emmanuel Macron’s decision to call snap parliamentary elections, the country now faces a hung parliament, a rising far-right influence, frequent government changes, and persistent budget gridlock. France’s public debt-to-GDP ratio has climbed above 116%, the fiscal deficit exceeds 5%, and the yield on 10-year French government bonds at one point broke through 4.13%.

This domestic political turbulence has once again weighed heavily on French bank stocks. Shares of BNP Paribas and Crédit Agricole each fell by as much as 4.4%, while Société Générale dropped up to 4%, dragging the broader STOXX Europe 600 Banks Index lower. Wall Street giant Goldman Sachs has previously cautioned that the rise of populist fiscal policies in France could further deteriorate the nation’s debt outlook. With 2027 presidential candidates now proposing sharply divergent approaches to spending, debt, and EU policy, bank stocks have once again become the most sensitive proxy for sovereign risk—the real danger lies not in their vast holdings of French government bonds, but in the secondary transmission of a rising sovereign risk premium into higher funding costs, weaker credit demand, and deteriorating asset quality.

The decline in French bank shares is fundamentally driven by resurgent market concerns over political instability ahead of a key debate scheduled for Thursday evening, where presidential hopefuls are expected to outline their competing visions for the country’s future. Several leading candidates are set to address a business leaders’ forum, presenting starkly different paths for the eurozone’s second-largest economy. The uncertainty surrounding who will succeed Emmanuel Macron next year—and what that means for France’s already strained public finances—continues to cast a shadow over the nation’s growth prospects.

Since Macron, a pro-business centrist, called for early elections more than two years ago, France has been mired in political upheaval, with bank stocks frequently emerging as the hardest-hit sector. This is a key reason why French lenders have largely underperformed their European peers. Unlike banks in Italy or Spain, which were at the epicenter of the eurozone sovereign debt crisis, French commercial banks hold significantly less of their own government’s debt—more than half of French government bonds are held by international investors. Analysts note that the genuine risk is not the banks’ exposure to government bonds, but the second-order effects, including rising refinancing costs and an economic slowdown fueled by the intensifying standoff between Macron’s centrist camp and far-right economic policies.
